According to MIT, this technology works even at small scale, with one the size of a suitcase able to desalinate 6 litres per hour, and only needing to be serviced every few years.

Here's a video detailing how it works.

Dumping salt into the sea like that causes major problems in the local ecosystem.

It depends where and how much. It would obviously need to be controlled, and spread out. You don't want to dump a lot of it into slow moving water, that's asking for problems. However, diluting it down, and dispersing it into stronger currents, over a large area should be fine (subject to proper environmental monitoring).
